OIL AND GAS SEPARATOR.

SPECIFICATION forming part 0f Letters Patent No. 537,388, dated. April 9, 1895. Application filed February 8,1895f Serial No.5371687. (No model.)

To @ZZ whom t may concern:

Be it known that l, JOHN W. HOUGH, a citizen of the United States, residing at Marion, in the county of Grant and State of Indiana, have invented certain new and useful Improvements in Oil and Gas Separators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in separators designed for use in oil wells, and the special object of my invention is to produce means for separating the gas from the oil and water of a well, the pressure of the gas constantly causing the Water and oil in mixture to be forced from a great depth in the ground, to the surface thereof.

A further object of this invention resides in the provision of a sliding valve fixedly held within a tube carried wit-hin an outer surrounding tube, the said valve being designed to regulate the flow of water and oil into the inner tube, which carries the water to the surface of the ground, and to be closed or opened by a running screw thread above the surface of the ground. I further provide a valve which is pivoted to a xed pin held to the walls of the inner sliding tube, and rests when shut on a valve seat of a tube which telescopes within the valve carrying tube and has a flange, which, when the valve is open abuts against the inwardly turned end of the said valve carrying chamber.

To these ends and to such others as the invention may pertain, the same consists further in the novel construction, combination and adaptation of the parts as will be hereinafter more fully described and then specifically deined in the appended claim.

I clearly illustrate my invention in the accompanying drawings, which with the letters of reference marked thereon form a part of this specification, and in which similar letters of reference indicate like parts throughout both views, in which- Figure l, is a sectional view longitudinally through the center of the valve and tubes. Fig. 2, is a cross sectional view on the line fc, a: of Fig. l. p

Reference now being had to the details of the drawings by letter, A, designates the ymetallic gas conveying tube, running the length of the well, within which tube or pipe an inner tube B is located and which is to carry the water and oil to the surface of the ground by the pressure of the natural gas at the lower end of the said inner tube.

O is a cylinder, connected to the lower end of the tube B, and is made up of two sections having screw thread connection. The upper section C of said cylinder carries the valve D, pivoted on the pin d which latter is held to the walls of the cylinderina tixed'relat-ion so that the valve may be raised and lowered with the cylinder, and more readily adjust itself to its seat.

E is a tube having a flange e and is designed to telescope within the cylinder C, and its top to form a seat for the Valve when closed. To the lower end of the pipe E is fastened by screw thread connection the union F having a series of apertures through which the water and oil are allowed to enter.

G is a cap which rests on the bottom of the well and supports the pipe carrying the valve seat.

The valve D has a series of recesses d about its circumference through which the water and oil pass into the cylinder, and the lower section of the cylinder has an inturned end which, when the valve is opened to its full extent, abuts against the flange of the valve seat pipe.

There is sufficient space between the inner tube `and the outside one to allow the gas to pass up to the surface of the ground where it is carried o through suitable pipes h, h. The inner tube, which carries the valve in the cylinder at the bottom, or near the bottom 4of the well, extends the entire length of the well and just above the surface of the ground it is connected by thread and screw to the collar J which is fastened by screw thread connection to the union K, which turns as a swivel in the screw threaded union L, screwed to the union M held to the tube R which lat- IOO ter is held by screw threaded connection to the cap S fastened to the outer gas conveying tube.

The operation of my invention will be readily understood, as when the separator is in place in a well, the lower end rests beneath the surface of the water and oil probably a number of feet, andthe valve is opened a suitable distance by turning the collar J, which raises or lowers the inner tube allowing the natural pressure of the gas to force the water and oil into the inner tube and tothe surface of the ground, andthe gas will be carried outside of the inner tube'to the surface, as described. v

Having thus described my invention, what I claim to be new, and desire to secure by Letters Patent, is-

in presence of two Witnesses.
